LED manufacturing technology** success or failure hit the mainstream lighting source

The LED manufacturing industry is facing a technological revolution that draws lessons from the experience of absorbing large-scale integrated circuit industries. This is not only full of challenges, but also brings tremendous opportunities for development. “Lighting is a basic human need. Traditional incandescent lamps, metal halide lamps, fluorescent lamps, etc. have existed and developed for many years and have been highly matured. There is no room for development in terms of light efficiency or cost. Incandescent lamps are low The typical representative of efficiency lighting has been eliminated and has become an irreversible inevitable trend.” Tang Guoqing, general manager of Cree Optoelectronics China Market, said at the “LED Illuminating Future” international symposium on March 16th. “At present, LED lighting is a new type of Solid-state lighting sources, performance is rapidly increasing, but the cost is constantly falling, which makes LED lighting into the general lighting market faster."

During the “Two Conferences” period of 2011, the energy saving demonstration project for semiconductor lighting applications put into use in the Great Hall of the People was completed. In the first phase of the 10,000 person auditorium and other important regional reconstruction projects, the original 1000W tungsten halogen lamp was replaced with a 160W LED lamp. Zhou Xuejun, Asia-Pacific marketing director from PHILIPS Lumileds, also stated that with the continuous decrease of Lm/$ of LED lighting, the light efficiency is continuously improving. By 2020, LED lighting will become the mainstream lighting source. However, the current LED industry is also facing many challenges, but behind the challenge is the existence of many opportunities for industrial development. The LED manufacturing industry can learn from many experiences and technologies in the large-scale integrated circuit semiconductor manufacturing industry. It can be said that the current LED manufacturing technology is brewing a technological revolution.

LED has great development and room for improvement in terms of epitaxial manufacturing, chip processing, and package testing. Taiwan Jingyuan Optoelectronics, as Taiwan's largest LED professional manufacturer, also occupies a very important position in the global LED manufacturing industry. Jing Mingjun, the general manager of Epistar, brought exciting news. Epistar’s new high-voltage LED provides a better solution for LED lighting from the perspective of chip design, especially the combination of Blu-ray and red light. LED can achieve the perfect unity of light effect, color temperature and color rendering. Dr. Xiao Guowei, the managing director of Jinko Electronics (Guangzhou) Co., Ltd., said that the technology core of the chip light source technology is a combination of high-power flip chip technology and large-scale integrated circuit technology, and will further move toward the HC-LED module, The development of light and intelligent light has systematic and complete technical advantages and development routes.

Wang Keyang, President of Veeco Greater China, stated at the “LED Illumination Future” International Symposium that “implementing general-purpose lighting must effectively reduce LED manufacturing costs. Effectively controlling the cost of epitaxy, high-capacity MOCVD must have a versatile production method. And Veeco's new MaxBright is a MOCVD device designed specifically for the general lighting market."

In response to the urgent need for LED performance improvement and cost reduction, KLA-Tencor, DISCO, and EV Group, specialized semiconductor device manufacturers, have provided specialized inspection and manufacturing for LED manufacturing. equipment.
